Algebra - Solving Inequalities

Рет қаралды 231,402

7 жыл бұрын

There is a now-famous rule about switching the inequality sign whenever multiplying or dividing both sides by a negative. But why? In another special video of Yay Math in Studio, we go over the rule, then apply it to solve several inequalities. The number line comes up too, so we explore that.
Then, we go over some expressions that come up in word problems, such as what "at least, at most, no more than" and "no less than" mean with inequality signs. YAY MATH!

Jackington Kellogers it’s not that it’s (-1) but because it’s negative don’t think about the number but think about if you are multiplying or dividing it by a negative

Did he just say Whatup? That was the best way to start a video, no wonder I replayed twice. He is so entertaining to watch yet he gets to the point. I wish you were my teacher! You are so funny & you teach very well. Also, wouldn't at least mean less because how can you guess you have more than what you think you have rather than underestimating, @yaymath?

@hewwothere3862 6 жыл бұрын

At least means at the minimum or not less than. I guess you know what "minimum" means don't you?

@thegoodlydragon7452 4 жыл бұрын

Why would a math teacher be less likely to say whatup? You know intellectuals are actually human, right? He's not a robot.

@ACHO Jesus is God. There is a trinity: The Father, the Son, and the Holy Spirit and they are all identified as God. I can argue that and win it with evidence from the Bible.

@ifyouseethisusernameyoumus1405 4 жыл бұрын

@ACHO I have so many verses that prove that you're wrong, not just John 1:1. John 1:1 John 3:16 Colossians 2:9 John 8:58 John 10:30 John 5:17-18 John 14:6 (He created life, and he is life.) 1 John 5:7 1 Timothy 3:16 Not only did He claim to be God, but He also claimed to have the power of God. He said He has the authority to judge the nations (Matthew 25:31-46). He claims the authority to raise people from the dead (John 5:25-29) and to forgive sins (Mark 2:5-7)-things only God can do (I Samuel 2:6; Isaiah 43:25). Now, where is your proof that Jesus isn't God?

If you have a job that requires you to think rather than simply move you body, whatever that job is, understanding how to think systematically is always beneficial. Likewise if you go into any natural science or engineering, then algebra itself will even be directly relevant to your work.

I dont understand, when he multiplyed 4 to both sides of the fraction, why did it become a 2, on the fraction to the right? And couldnt you just make the fractions have a common denominator and then solve?

@tuxedo2037 7 жыл бұрын

It became a 2 because 4 divided by 2 is 2. Even if you made the denominator the same (like 4) you will still get 2x - 6 > 2x-6 which cannot be solved

in an inequation like 1/1-2x > 1/2x+3, why can't I just raise both sides to -1 so I can get 1-2x > 2x+3 ??

This is embarrassing but I'm a grade 12 student who never really understood the whole sign switch assignment. I think i get it I'm not sure yet I'll have to do some questions myself BUT I do have a doubt, For trying to balance out fractions can we take LCM of both sides?
